What might link these
Higher egg yields may reflect industrialized agriculture, which could correlate with paper-intensive industries like publishing or packaging. GDP and population controls reduce but don’t eliminate this link, suggesting other confounders like education levels or trade openness might still drive the association.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. Correlation alone doesn’t prove causation; the link could reflect unmeasured factors like technological development or export-oriented economies.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
